EXTERNAL PHONEBOOK (LDAP)
OmniTouch 4135 IP has support for an external phonebook. This means it can 
communicate with a catalog server according to LDAP (Lightweight Directory Access 
Protocol). To make the external phonebook accessible, an administrator must activate 
and congure the LDAP function in OmniTouch 4135 IP.
An LDAP database can hold thousands of contacts and for this reason, OmniTouch 
4135 IP includes a search function to lter the content of the database dynamically, 
based on the search characters you enter. 
When you nd the right contact, you can open it with OK. When you have done this, you 
can choose which of the contact’s telephone numbers you want to ring (for instance, 
work, mobile or home).
 Please note, the administrator has the option to congure the function in different 
ways; this means it may function differently to the way described here. 
  The administrator can determine in which database eld your search characters 
will be used, the number of hits that are to be displayed in OmniTouch 4135 IP 
and the information that is to be displayed (name, company, department, telephone 
number).
  Contact the company’s telephone or network manager for information on how LDAP 
is congured for your OmniTouch 4135 IP.
